Bulk Bag Gantries are used to lift Bulk Bags (aka Super Sacks) into position over a Ground Hopper, and usually used in conjunction with Gruber Systems’ Autocaster Ultra continuous casting systems.

Lift and position Bulk Filler Bags ("Supersacks") over Gruber Ground Hoppers for added filler capacity, greater convenience - and eliminate production interruptions required when you are manually loading bulk fillers into a Ground Hopper or other filler storage, metering or conveying feeder. For Gruber Autocaster customers, this is a time and money saving way to keep your bulk fillers loading continuously without the need to pause your Autocaster to load more bulk fillers.

Bulk Bag Gantries are used to lift Bulk Bags (aka "Super Sacks") into position over a Ground Hopper, and usually used in conjunction with Gruber Systems’ Autocaster Ultra continuous casting systems. Ground Hoppers provide a longer term supply of fillers to the metering hoppers mounted on top of the Autocaster system - so that the continuous casting capability of the Autocaster is not interrupted by the need to resupply the metering hoppers. Depending on your physical layout, and flexibility desired of handling these bulk bags, you have a choice of Ground Hoppers and Gantries, as well as associated Bulk Bag Pallet Roller Conveyors to help automate the staging of bulk fillers in your operation.

Generally, bulk bags are staged below the gantry, or are transported to that location with a bulk bag conveyor track (see illustration at right). The bags are often stored in a remote location, and the bulk bag conveyor can simplify the transfer of the bag to where the Ground Hopper is located. Alternatively, fork lifts can transport these bulk bags as well, but when a fork lift does not have access to the staging area below the Ground Hopper, Bulk Bag Conveyor's offer a very convenient method of moving bulk fillers into position.

Once the bulk bags are positioned below the hoist, the bulk bag is hoisted off its pallet, and the trolley moves the bulk bag into position immediately above the Ground Hopper. As shown in the illustration at right, the hoist will suspend the bulk bag over the Ground Hopper until the bulk bag is emptied. Once emptied, the bag is lowered, and a new bag is picked up and placed into position to continue the production process.

  • Gantries are manufactured from heavy-duty steel components and finished in powder-coat.
  • Cable trolleys provided to carry and guide hoist’s power supply cord
  • Bulk bags can be lifted from the ground with the hoist – no forklift access to ground hoppers required

Bulk Bag Suspender Cross Frame included with each Bulk Bag Gantry

Each of the two Bulk Bag Gantries shown below include this Bulk Bag Suspender Cross Frame to attach the hoist and trolley to the Bulk Bag. The hoist lowers the suspender frame down, and the frame is attached to each corner point on the Bulk Bag. Once attached to the bag, the bag is lifted, and the trolley moves the bag into position above the Ground Hopper.

Ground Hoppers

Gruber Ground Hoppers meter and convey bulk fillers to the point of use (usually a Gruber Autocaster continuous casting machine. Ground Hoppers are offered for a variety of applications - including Cultured Marble, Solid Surface, Polymer Concrete and other Bulk Powder metering or conveying requirements - for all types of bulk fillers such as powders, granules, aggregates and even larger stone.

Bulk Bag Suspenders mount to the top of Ground Hoppers to stage an extra super sack full of filler above the Ground Hopper
 

Bulk Bag Suspender Frame

The optional Bulk Bag Suspender Frame allows the option of mounting larger, more economical bulk bags (“Super Sacks”) above Gruber’s Ground Hopper™ bulk solids conveyors. Mounting large bulk bags reduce interruptions during the manufacturing process, and reduces labor costs normally associated with manual loading of a metering or feed hopper – particularly when compared to manual loading of smaller bulk material bags. Automation of the bulk material handling system also results in a cleaner, safer working environment and more efficient manufacturing workflow.
